1:进入php源码目录下的ext.如 /usr/local/php-8/ext
2.生成自定义扩展的名字 php ext_skel.php --ext python
3.撰写函数原型，编辑 python.stub.php
3.1 默认是test1，test2
<?php
/** @generate-function-entries */
function all(array $arr): bool {}
function any(array $arr): bool {}
4:根据 python.stub.php 生成 python_arginfo.h
php ../../build/gen_stub.php python.stub.php
5.实现函数逻辑，编辑 python.c
PHP_FUNCTION(all)
{
zval *input;
zval *item;
int result = 1, item_result = 1;
HashTable *htbl;
ZEND_PARSE_PARAMETERS_START(1, 1)
Z_PARAM_ARRAY(input)
ZEND_PARSE_PARAMETERS_END();
htbl = Z_ARRVAL_P(input);
ZEND_HASH_FOREACH_VAL(htbl, item) {
item_result = zend_is_true(item);
result &= item_result;
} ZEND_HASH_FOREACH_END();
RETURN_BOOL(result);
}
/* {{{ void any() */
PHP_FUNCTION(any)
{
zval *input;
zval *item;
int result = 0, item_result = 0;
HashTable *htbl;
ZEND_PARSE_PARAMETERS_START(1, 1)
Z_PARAM_ARRAY(input)
ZEND_PARSE_PARAMETERS_END();
htbl = Z_ARRVAL_P(input);
ZEND_HASH_FOREACH_VAL(htbl, item) {
item_result = zend_is_true(item);
result |= item_result;
} ZEND_HASH_FOREACH_END();
RETURN_BOOL(result);
}
8:加入到php.ini
php --ini # 定位你的php.ini文件
#添加
extension=python.so
#查看是否成功
php -m | grep python
9: 测试
php -r "var_dump(all([]));"
php -r "var_dump(any([]));"
